A GENERATIVE DRAWING INSTRUMENT
Give your drawings a voice.
FILIGRANA is a free, open-source instrument that turns drawings into gentle, evolving music in your browser. Three independent voices wander over the lines, turning each image into a sound world that can be listened to, shaped, and rendered.
The instrument finds ink, traces it into connected paths, and follows their intersections. Line length shapes resonance and pitch; your chosen instruments, scale, and octave color the result. Each traveller moves independently, so the drawing can unfold differently with every journey.
Listen to sketches in a new way, create ambient compositions, or make sound for installations, films, and quiet spaces. Adjust the voices and effects, then render an MP3, high-resolution WAV, or video with sound.
